Abstract
A stiff anti-backlash gear unit comprising two or more high ratio reducer assemblies provides an energy efficient, low backlash, speed reducer. The gear unit is assembled in such a way as to eliminate backlash without any preloading and may be configured as a conventional, planetary or star gear with co-axial, spaced, angled or multiple output shafts.
Claims20
An apparatus comprising:
- a first engaging member, a second engaging member, a carrier member, one or more first reducer assemblies, and one or more second reducer assemblies;
- each reducer assembly comprises a first reducer engaging member defining an input, a second reducer engaging member defining an output, and a reference member;
- and wherein:
- the first engaging member simultaneously engages all first reducer engaging members;
- the second engaging member simultaneously engages all second reducer engaging members;
- the number of turns applied to the input of each reducer assembly with respect to the number of turns resulting at the output of each reducer assembly defines a reduction ratio for each reducer assembly;
- all first reducer assemblies provide a common first reduction ratio;
- all second reducer assemblies provide a common second reduction ratio.

An apparatus comprising:
- a first engaging member, a second engaging member, a carrier member, and two or more reducer assemblies each comprising a first reducer engaging member defining an input, a second reducer engaging member defining an output, and a reference member;
- and wherein:
- the first engaging member simultaneously engages all first reducer engaging members;
- the second engaging member simultaneously engages all second reducer engaging members;
- the number of turns applied to the input of each reducer assembly with respect to the number of turns resulting at the output of each reducer assembly defines a reduction ratio for each reducer assembly.
2 more elements
A method comprising:
- providing a first engaging member;
- providing a second engaging member;
- providing a carrier member;
- providing two or more reducer assemblies each comprising an input portion, an output portion and a reference portion and wherein the number of turns applied to each input portion with respect to the number of turns resulting at each output portion defines a reduction ratio for the corresponding reducer assembly;
- simultaneously engaging one or more input portions to the first engaging member and the corresponding output portions to the second engaging member whereby all backlash is removed for one direction of rotation of the first engaging member;
- and simultaneously engaging all remaining input portions to the first engaging member and the corresponding output portions to the second engaging member whereby all backlash is removed for the opposite direction of rotation of the first engaging member.
